vauxhall cavalier 1.8lsi not firering on number4 pot (cylinder)?
when idleing it is not firering on number 4cylinder.The sparkplug is not black or wet,you can remove the HT leed of the s/plug and the revs stay the same.
try changing the plug, if that dont work try changing the lead after making sure it is secured to the plug and distributer,if that does,nt work try another distributer cap making sure that all the leads are put back in the same order they came off.

Is fuel getting into cylinder ? see if plug gets wet with ht lead disconnected from it. Could be weakening fuel pump or injector blockage.
